Title: Transmission gear shifts
IPC: E21B17/042
Filed: 1971-09-29
Abstract: 1335885 Positive clutches; change speed gear boxes EATON CORP 29 Sept 1971 [30 Sept 1970] 45442/71 Headings F2C and F2D A synchronizing device between a first ratio gear and a second ratio gear which is always rotating slower has coupling means moved by shift means so arranged that the frictional drag of the shift means against the coupling will assist deceleration of a shaft during engagement of the second' gear but will not materially inhibit acceleration of the shaft during engagement of the first gear with it. A main transmission 1 having a shaft 2 driven by an input shaft 5 is followed by an auxiliary unit 21 having a shaft 23. The main unit has countershafts 8, 9 and the auxiliary unit has countershafts 24, 26. The shaft 2 is supported in a bearing 4A wherein a flange 66 ahead of the bearing on the shaft 2 has a conical portion 68 of a flange 67 rearward of the bearing projecting towards it with a pressure fitting 69 with a corresponding conical portion having axial springs 71 interposed to absorb permitted radial movement of the shaft. The synchronizing device is provided between a first auxiliary gear 31 clutchable to the shaft 2 and supported by countershaft gears 27, Fig. 3, and a second auxiliary gear 32 always rotating at a slower speed and clutchably driven by a slider 46 rotatably connected to the shaft 2 while the gear 32 is supported by countershaft gears 28. The slider 46 has a recess 51 in which a flange 49 of the gear 31 is held by a snap ring 52, Fig. 1A so that a groove 56 is formed to receive a clutch fork 57 actuated by a cylinder 60. Teeth 41, 42 clutch the gear 31 to the shaft 2 while teeth 47, 48 clutch the slider 46 to the gear 32. From the neutral position, Fig. 1A, movement of the fork 57 to the right, Fig. 1, will provide frictional drag on the slider 46 as it moves towards the slower gear 32 for engagement, but movement to the left will only cause drag on the gear 31 then free on the shaft 2 which is thus not impeded from being speeded up before engagement of the teeth 41, 42 to rotate the faster gear 32.

Abstract: 1403632 Block polymers containing conjugated diene, α-methyl styrene and styrene units DENKI KAGAKU KOGYO KK 28 Sept 1973 [29 Sept 1972] 45537/73 Heading C3P A block polymer has a polymeric chain which comprises a central polymer block comprising a major proportion of conjugated diene units, at least one polymer block attached to the central block consisting of alphamethyl styrene units and attached to this block or blocks a terminal tapered copolymer block comprising alpha methyl styrene and styrene units, the proportion of alpha methyl styrene units in this block decreasing towards its free end. Overall, the block copolymer peferably contains 15-80 wt. per cent of the diene units and 15-60 wt. per cent of the alpha methyl styrene units. The polymers may be prepared by completely polymerizing a conjugated diene using a polyfunctional organolithium compound as initiator, adding alpha methyl styrene and polymerizing it in the presence of a polymerization promoter at -10 to 30‹ C. and adding styrene when the polymerization of the alpha methyl styrene has reached the monomer equilibrium concentration, and substantially completing the polymerization of the alpha methyl styrene and styrene. Examples of promoters are others, amides or amines. The polymerization is preferably carried out in a non-polar solvent.

Abstract: 1321676 Holography RCA CORPORATION 30 Sept 1970 [30 Sept 1969] 46440/70 Heading G2J  Phase holograms recorded on a tape are read out by illuminating with a read out beam 502, the reconstructed beam 506 emanating from the hologram 504 at an angle to the normal, the hologram 504, read out beam 502 and a viewing means (512) being so oriented one to the other that twisting movement of the tape 504, P 1  to P 2 , during read out gives rise to a minimum change in angle of the reconstructed beam for a given change in angle of incidence of the read out beam. The phase hologram is produced with both information and reference beams angled to the normal to the record medium preferably with the normal bi-secting that angle. Streaks caused by the diffraction effects of scratches on the tape surface are formed in an area entirely outside the area of the reconstructed image. If desired the wavelength of the readout-beam may be different from that of the beams used in recording and consequently the angle the read-out beam makes to the hologram is different from that made by the recording reference beam.

Abstract: 1,125,588. Pipe joints. UNION CARBIDE CORP. 9 Nov., 1965 [10 Nov., 1964], No. 47385/65. Heading F2G. [Also in Division B3] A vacuum insulated container has inner and outer walls 10 and 12 connected to a common neck tube 14 by virtue of corrugations, in the flanges 16 and 18 of the walls, which mate with annular recesses in the tube. The tube 14 is joined to flanges 18 and 16 by magnetically deforming the flanges inwardly against the neck tube. When the walls 10 and 12 are of aluminium and the tube is a nickel base alloy or a plastics material, the assembly is positioned within a solenoid with a mandrel supporting the tube and pulsating electrical energy is supplied to the solenoid. Eddy currents deform the shells inwardly to produce a joint profile as, for example, shown in Fig. 5. When the walls are of stainless steel or a material having a relatively low conductivity, a driving ring 20 of aluminium or copper is used to drive the appropriate flange against the tube. An epoxy based adhesive can be used in conjunction with the joints, the adhesive being applied before the deformation step.

In the neutral position of control valve 3 the axes of pinions 4, 5, 6 lie in a common plane, as shown. Should an input pulse now be applied to motor I to cause pinion 4 to rotate by an angular step, pinion 6 pivots about its point of engagement with pinion 5, thus effecting an axial displacement of control piston rod 8. The resulting rotation of motor 2 causes pinion 6 to pivot about its point of engagement with pinion 4 until the control piston is restored to its neutral position. The spacing between the pinion axes is adjustable to permit the pinions to be changed to give different transmission ratios. The hydraulic motor 2 may be of radial piston type, the shaft output of which causes movement of a numerically controlled machine tool.
